Tidy up of div and mod operators (C implementation was previously inconsistent with ocaml etc.). Rename div and mod builtins to ediv_int/emod_int and tdiv_int/tmod_int and add corresponding implementations. Add a test with negative operands. This will break existing models but will mean users have to think about which versions they want and won't accidentally use the wrong one.
